Abstract
A traction control and active suspension for land vehicles of the type having ground-engaging wheels and a fluid motor for each wheel, located on a wheel mount movable with respect to a vehicle frame, wherein a suspension spring and fluid cylinder are interposed between the wheel mount and the frame, and fluid pressure applied to the wheel motor is also applied to the cylinder such that when traction is lost, the fluid pressure drops in the cylinder, allowing the spring to extend the wheel mount towards the ground to regain traction. A fluid valve is provided to flush the fluid cylinder when the vehicle transmission is in a neutral condition in one embodiment, while an alternative embodiment uses a pair of diverter valves to accomplish flushing of the fluid cylinders.
